SAFETY
1.1 SAFETY ALERT SYMBOL
The Owner/Operator’s manual uses this symbol to alert
you of potential hazards. Whenever you see this symbol,
read and obey the safety message that follows it. Failure
to obey the safety message could result in personal injury,
death or property damage.
CAUTION
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury.
WARNING
Indicates a potentially hazardous situation that, if not
avoided, could result in death or serious injury.
The engine on your
power equipment, like
most outdoor power
equipment, is an internal
combustion engine that
burns gasoline or diesel
fuel (hydrocarbons).
Therefore, your power
equipment must be
equipped with a spark
arrester mufer in continuous effective working order. The
spark arrester must be attached to the engine exhaust
system in such a manner that ames or heat from the
system will not ignite ammable material.
Failure of the owner/operator of the equipment to comply
with this regulation is a misdemeanor under California law
and may also be a violation of other state and/or federal
regulations, laws, ordinances, or codes. Contact your
local re marshal or forest service for specic information
about which regulations apply in your area.
The standard mufer installed on the engine is not
equipped with a spark arrester. One must be added before
using this machine in an area where a spark arrester is
required by law. Contact the local authorities if these laws
apply to you. See your authorized engine dealer for spark
arrester options.
1.3 BEFORE OPERATING
DANGER
Indicates an imminently hazardous situation that, if
not avoided, will result in death or serious injury.
1.2 EMMISSION INFORMATION
Under California Law and the laws of several other states,
you are not permitted to operate an internal combustion
engine using hydrocarbon fuels on any forest covered,
brush covered or grass covered land or on land covered
with grain, hay or other ammable agricultural crops,
without an engine spark arrester in continuous effective
working order.
